Description
Cross Reference to Related Applications
According to 35u.s.c. ≡119 (e), the present application claims priority from U.S. provisional application No. 63/228,659 filed on 8/3 of 2021, the entire disclosure of which is expressly incorporated herein by reference.
Technical Field
The exemplary embodiments relate generally to manufacturing technology and, more particularly, to tool control and management in a manufacturing environment.
Background
In many manufacturing and assembly environments, such as automotive, aerospace, and large household appliance assembly environments, it is desirable to ensure that a powered rotary tool (e.g., a nut runner, an electric screwdriver, etc.) is operated at an appropriate setting (e.g., torque setting, etc.) for a given task performed by a manufacturing worker using the tool. Tools that operate with incorrect settings can create a number of problems. For example, a single tool with an improper torque setting may over-tighten a fastener (e.g., a bolt, screw, etc.), which may result in damage to the manufactured product. In addition, such over tightening may cause the threads of the fastener to become cross-threaded or chipped, which may reduce the tightening force that the fastener can apply and may lead to early failure of the fastener. Another common drawback is under-tightening (too low torque), in which case the fastener may become loose, even falling off during use. Depending on the type of product being manufactured, such fastener problems can reduce the overall reliability and life of the product. Thus, there is a great need for a technique that operates to ensure that tools on, for example, a manufacturing floor are properly set for a given task.
In addition, it is desirable that power rotary tools used in manufacturing environments be low cost. However, many low cost power rotary tools are designed for the consumer market, with importance placed on flexibility and ease of use. Thus, these low cost power rotary tools allow easy modification of settings. The use of such tools, while available at low cost, can be problematic in a manufacturing environment because the settings on the tool can be easily changed. As a result, supervisors and administrators may be required to constantly monitor tool settings by performing spot checks on the tools. Such spot checks may require actual operating tools or very close tools in order to be able to determine the current setting.
Accordingly, there is a need for improved areas of rotary tool setting management, particularly in support of operations in a manufacturing environment.
Disclosure of Invention
According to some exemplary embodiments, a rotary power tool assembly is provided that includes a rotary power base and a plurality of modular drive heads. The rotating power base may be configured to rotate the spindle in response to actuation of the control switch. The modular drive head may be configured to be detachably coupled to the rotodynamic base and the spindle. The modular drive head may include a torque control clutch, a working tip, and a torque value indicia. The torque control clutch may include an input drive configured to be detachably coupled to the spindle and an output drive operatively coupled to the working tip. The input drive may be operably coupled to the output drive to selectively rotate the output drive in response to rotation of the input drive. The torque control clutch may be non-adjustably configured to perform a torque limiting slip event in response to the output driver experiencing a torque exceeding a discrete torque value, the event preventing further rotation of the output driver despite continued rotation of the input driver. The torque value indicia may be externally visible and the torque value indicia may include visible features associated with discrete torque values.
According to some exemplary embodiments, a rotary power tool accessory system is provided. The system may include a first modular drive head and a second modular drive head. The first modular drive head may be configured to be detachably coupled to the rotodynamic base. The first modular drive head may include a first torque control clutch and a first torque value indicia. The second modular drive head may be configured to be detachably coupled to the rotodynamic base. The second modular drive head may include a second torque control clutch and a second torque value indicia. The first torque control clutch may be configured to prevent rotation of the first working tip of the first modular drive head in response to the first working tip being subjected to the first discrete torque value. The first torque value indicia may include a first visible feature associated with the first discrete torque value. The second torque control clutch may be configured to prevent rotation of the second working tip of the second modular drive head in response to the second working tip being subjected to the second discrete torque value. The second torque value indicia may include a second visible feature associated with a second discrete torque value. The second discrete torque value may be different from the first discrete torque value, and the second visible feature is visually different from the first visible feature.
A method for manufacturing compliance is provided. The method may include visually verifying that a first rotary power tool assembly operating on a first manufacturing task has a first torque value indicia with a first visual characteristic and visually verifying that a second rotary power tool assembly operating on a second manufacturing task has a second torque value indicia with a second visual characteristic. The first visual characteristic may indicate that the first rotary power base of the first rotary power tool assembly is attached to a first modular drive head having a first non-adjustable torque control clutch. The first non-adjustable torque control clutch may be configured to limit the applied torque to a first discrete torque value associated with the first visual characteristic and selected for the first manufacturing task. The first modular drive head may be detachably coupled to the first rotodynamic base. The second visual characteristic may indicate that a second rotary power base of a second rotary power tool assembly is attached to a second modular drive head having a second non-adjustable torque control clutch that limits the applied torque to a second discrete torque value associated with the second visual characteristic and selected for a second manufacturing task. The second modular drive head may be detachably coupled to the second rotodynamic base. The second discrete torque value may be different from the first discrete torque value, and the second visible feature may be visually different from the first visible feature.

Detailed Description
Some example embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all example embodiments are shown. Indeed, the examples described and depicted herein should not be construed to limit the scope, applicability, or configuration of the disclosure. Rather, these exemplary embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout. Further, as used herein, the term "or" should be interpreted as a logical operator whose result is true whenever one or more of its operands are true. As used herein, operable coupling should be understood to refer to a direct or indirect connection that, in either case, enables functional interconnection of components operably coupled to one another.
Various exemplary embodiments described herein address the technical problem of maintaining manufacturing program compliance by providing tools and accessories that support such compliance. In this regard, according to some exemplary embodiments, a rotary power tool assembly is provided that includes a rotary power base (e.g., a motorized portion of a power screwdriver, nut runner, etc.) and a plurality of different attachable modular drive heads, wherein each drive head has a fixed torque control with a different discrete torque value. Thus, according to some exemplary embodiments, each modular drive head provides a single, fixed maximum allowable torque that can be output from the rotary power tool assembly when the modular drive head is connected to the rotary power base. Since each modular drive head provides only a single torque control option according to some exemplary embodiments, once attached to the rotary power base, there is no risk of the manufacturer accidentally (or intentionally) changing the torque setting on the rotary power tool assembly. Thus, manufacturing compliance is maintained or improved.
In addition, each attachable modular drive head may include a highly visible torque value indicia that includes a visible feature related to the torque value (e.g., torque threshold) of the modular drive head. For example, the torque value indicia may be a colored ring (e.g., yellow, red, green, etc.) that encircles the modular drive head to indicate the torque value employed by the modular drive head. The torque value indicia may be formed to be highly visible, e.g., of sufficient size to be visible from a few feet away (e.g., 10 feet or more). Thus, when the modular drive head is connected to the rotary power base, the torque value indicia may be used to quickly and visually determine at which torque value the resultant rotary power tool assembly is operating. Thus, torque value represents the ability to facilitate easy inspection and verification of torque values of rotary power tool components in a manufacturing environment to ensure that the proper torque value tool is used in association with the proper task. This again supports improved manufacturing compliance and consistency, for example by allowing a supervisor to quickly determine that a tool with an incorrect torque value is being used for a certain task based on the visual characteristics of the torque value markers.
In light of the foregoing, FIG. 1 illustrates an exemplary rotary power tool assembly 10 according to some exemplary embodiments. In this regard, the rotary power tool assembly 10 may include a rotary power base 20 and a modular drive head 40. Modular drive head 40 may be removably connected to rotodynamic base 20 at interface 60. As further described herein, the modular drive head 40 may be detachable or separable from the rotary power base 20, and different modular drive heads may be connected to the rotary power base 20 to vary the torque value of the rotary power tool assembly 10.
According to some exemplary embodiments, the rotating power base 20 may be the power and motorized portion of a power screwdriver, drill, nut runner, or the like. The rotodynamic base 20 may include a plurality of components for operation, which may be disposed within the housing 22. Some exemplary components include a battery 26, a control circuit 28, a motor 34, and a spindle 36.
The battery 26 may be one example of a power source for the rotating power base 20. The battery 26 allows the rotodynamic base 20 to be cordless and therefore easy to use and operate, irrespective of the presence of a tether in the form of a wire. However, it should be understood that the exemplary embodiments may be implemented with a rotating power base 20 that is wired or uses a power source (e.g., a pneumatic source) other than or in addition to a battery. The battery 26, which is a power source, may provide power to the control circuit 28, the motor 34, and the output device 32. The battery 26 may be recharged as a permanent part of the rotodynamic base 20 or as a removable part that may be removed and replaced with a similar battery (e.g., fully charged).
The control circuit 28 may include a plurality of electronic components that support the operation of the rotary power base 20 and the rotary power tool assembly 10, as described herein. The control circuit 28 may include one or more integrated circuits including logic code (hardware or software code) for controlling the operation of the rotodynamic base 20. In this regard, the control circuit 28 may include a processor, which may be implemented as, for example, a Field Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC). In the alternative, the processor may be a software programmable processing device that executes software or firmware code retrieved from the memory device. The control circuit 28 may be configured to receive an input and provide an output based on the input.
In this regard, the control switch 30 may provide a signal to the control circuit 28, which may be used as an input. For example, when the user depresses the control switch 30 (operates as a trigger), a signal may be provided as an input to the control circuit 28, and in response, the control circuit 28 may provide an output that allows power to be provided to the motor 34 to rotate the spindle 36. In addition, when the user releases the control switch 30, the control circuit 28 may detect a change in the provided signal and stop the power to the motor 34.
In addition, the control circuit 28 may be configured to control the output device 32. According to some exemplary embodiments, the output device 32 may be a light (e.g., a Light Emitting Diode (LED)) that may be controlled to provide information to a user regarding the operation of the rotating power base 20. In this regard, according to some example embodiments, the control circuit 28 may control the output device 32 to illuminate in different colors based on the operating conditions of the rotodynamic base 20 (e.g., low battery-requiring charging, battery fully charged, internal errors, etc.).
The motor 34 may be an electric motor configured to rotate the spindle 36 to provide a rotational output for rotating the power base 20. Alternatively, the motor 34 may be, for example, a pneumatic motor. The motor 34 may operate at a single rotational speed. However, according to some exemplary embodiments, the motor 34 may be a two-speed or variable speed motor, and the control circuit 28 may be configured to receive input (e.g., from the control switch 30) and control operation of the motor 34 based on functionality provided by the motor 34.
The spindle 36 may be rotated by the motor 34, and the spindle 36 may be the rotational output of the rotodynamic base 20. According to some exemplary embodiments, the main shaft 36 may include a coupler 62. Coupler 62 may be configured to engage with a complementary coupler 64 (via interface 60) to form a rotational connection between rotodynamic base 20 and modular drive head 40.
As described above, modular drive head 40 is removable from rotodynamic base 20 at interface 60. In this regard, the modular drive head 40 and the rotodynamic base 20 may include various connection features, including connectors 62 and 64, that operate to secure the modular drive head 40 to the rotodynamic base 20 until a disassembly operation is performed. According to some exemplary embodiments, modular drive head 40 may be removable from rotodynamic base 20 without the use of tools (e.g., by hand). In this regard, the modular drive head 40 may include, for example, a stationary collar that engages and engages with complementary features of the rotating power base 20 to secure (e.g., by rotational, possibly threaded engagement) the modular drive head 40 to the rotating power base 20.
Modular drive head 40 may include a torque control clutch 44, a reduction gear 45, a collet 46, and a working tip 48. As shown in fig. 1, a rotating member or shaft extends from the coupler 64 through the modular drive head 40 to the working tip 48 and is acted upon, for example, by the torque control clutch 44 and the reduction gear 45 to change the rotational operation from an input at the coupler 64 to an output at the working tip 48.
Working tip 48 may be directly or indirectly engaged with a fastener or working surface to perform an operation (e.g., a task). Thus, the working tip 48 may be, for example, a drill bit secured by the collet 46, including a working end (e.g., a screwdriver bit, drill bit, sleeve bit, etc.) that is directly coupled to a fastener or working surface. Alternatively, the working tip 48 may be a tang or post to which a drill bit or socket is secured, and the drill bit or sleeve directly engages the fastener or working surface.
The reduction gear 45 may be configured to receive input rotation at a given rotational speed and provide rotational output at a lower speed. Although the reduction gear is shown on the output side of the torque control clutch 44, the reduction gear 45 may alternatively be arranged on the input side of the torque control clutch 44.
The torque control clutch 44 may be a mechanical device that operates to disengage or "slip" when torque exceeding a discrete torque value (e.g., a threshold torque) is applied to the output drive 43, for example. In this manner, the torque control clutch 44 may be configured to provide torque control to the rotary power tool assembly 10.
Controlling the torque applied while performing certain tasks may avoid many of the problems described above, including damage to the manufactured product. For example, without torque control, the fastener cannot be tightened to a uniform torque, resulting in potential quality control problems. Further, torque control may ensure that the fastener is driven to a desired depth without over-tightening (e.g., which may result in leaving an exposed fastener head or unsecured head, allowing movement and vibration) or over-tightening (e.g., which may result in the fastener passing completely through the surface being attempted to be secured, or the fastener becoming threaded or chipping and providing reduced securing force).
The torque control clutch 44 may include an input drive 42 configured to be detachably coupled (directly or indirectly) to the main shaft 36 and an output drive 43 operatively coupled to a working tip 48. The input drive 42 may be operatively coupled to the output drive 43 by a torque control clutch 44. Accordingly, the torque control clutch 44 may selectively rotate the output driver 43 in response to rotation of the input driver 42 when the torque applied to the output driver 43 does not exceed a discrete torque value. In other words, the torque control clutch 44 may be configured to perform a torque limiting slip event in response to the output driver 43 experiencing a torque exceeding a discrete torque value, which event prevents further rotation of the output driver 43, despite continued rotation of the input driver 42. The discrete torque values for the modular drive head 40 may be determined by the mechanical configuration of the torque control clutch 44, which may be stationary according to some exemplary embodiments. The discrete torque value may be selected as a particular torque value, such as newton meters, rather than a relative torque setting as in a plurality of options provided on some adjustable torque control tools. According to some exemplary embodiments, the torque control clutch 44 may be non-adjustably configured, so that discrete torque values may be set at the time of manufacture of the modular drive head 40 and may not be changed later. As described above, the inability to change the discrete torque values of modular drive head 40 prevents torque setting changes that can lead to manufacturing compliance issues.
Alternatively, according to some exemplary embodiments, the discrete torque values of modular drive head 40 may be adjusted after manufacture. In such an embodiment, for example, only the tool may be used for adjustment, and possibly only when the modular drive head 40 is not connected to the rotational power base 20. For example, only a single adjustment tool may be used to adjust the modular drive head 40. Access to such adjustment tools may be limited to, for example, a supervisor to prevent unauthorized or incorrect adjustments from being made. According to some exemplary embodiments, the separate adjustment tool may be a spring compression tool, which may be used to adjust the discrete torque values. Such spring compression tools typically do not allow production line personnel to adjust discrete torque values while the assembly line is in operation. To support exemplary embodiments that allow for adjustability of discrete torque values, as described further below, torque value indicia 50 may be removed and replaced on modular drive head 40, wherein torque value indicia 50 is encoded into an adjusted discrete torque value.
According to some exemplary embodiments, modular drive head 40 may be locked to rotodynamic base 20 by a locking mechanism 80. In this regard, to prevent unauthorized replacement of the modular drive head by a manufacturer, the locking mechanism 80 may require the key 88 to unlock and remove the modular drive head 40 from the rotary power base 20. The key 88 may be carried and controlled by a supervisor to limit or prevent access to the key 88 by a manufacturer using the rotary power tool assembly 10. In this way, the key 88 may be separated from the rotary power tool assembly 10. The locking mechanism 80 may include a locking coupler 82 on the rotating power base 20 side of the interface 60 and a locking coupler 84 on the modular drive head 40 side of the interface 60. According to some exemplary embodiments, key receiving holes 84 may be provided on one of either side of the interface to allow for mechanical release of modular drive head 40 from rotary power base 20 upon engagement (e.g., insertion) of key 88 into holes 84. According to some exemplary embodiments, modular drive head 40 may be latched into engagement (e.g., locking engagement) with rotodynamic base 20 upon attachment, and thus, key 88 may be required for removal (or disassembly) rather than attachment.
According to some exemplary embodiments, modular drive head 40 may also include a torque control sensor 90. The torque control sensor 90 is operatively coupled to the torque control clutch 44 to enable detection of when the torque control clutch 44 is executing a torque limiting slip event. For example, a torque control sensor 90 may be coupled in the mechanism of the torque control clutch 44 to detect a torque limiting slip event. Alternatively, the torque control sensor 90 may be operatively coupled to the output driver 43, and the torque control sensor 90 may be configured to detect when the output driver 43 is not rotating (e.g., due to the occurrence of a torque limiting slip event). The torque control sensor 90 may be configured to send a signal to the control circuit 28 indicating that the output driver 43 is not rotating, for example, due to the occurrence of a torque limiting slip event. Accordingly, the control circuit 28 may be configured to receive a signal or communication indicating that a torque limiting slip event is occurring and, in response to receiving the communication and a hold actuation of the control switch 30, interrupt power delivery to the motor 34 driving the spindle 36 to stop rotational movement of the spindle 36. According to some example embodiments, the control circuit 28 may be configured to receive a signal from the torque control sensor 90 indicating that the output driver 43 is not rotating, and to receive a signal from the control switch 30 indicating that the control switch 30 is actuated (e.g., depressed). In this regard, when the output drive 43 is not rotating and the control switch 30 is actuated, it may be assumed that the torque-limiting slip event has been performed by the torque-control clutch 44, and thus the power delivery to the motor 34 may be interrupted. Such interruption of power delivery to motor 34 may continue until control switch 30 is no longer actuated (e.g., released). Upon subsequent actuation of the control switch 30, electrical power may be delivered to the motor 34.
Modular drive head 40 may also include torque value indicia 50. According to some exemplary embodiments, the torque value indicia 50 may be an externally visible indicator disposed on the modular drive head 40. Torque value indicia 50 may include visual features related to discrete torque values of modular drive head 40. In this regard, the visible characteristic of the torque value indicia 50 may be color. In this way, a modular drive head 40 with a green torque value indicia 50 will have a different discrete torque value than a modular drive head 40 with a red torque value indicia 50. As such, the color of the torque value indicia 50 may be used as an indication of the discrete torque values applied by the rotary power tool assembly 10.
According to some example embodiments, other types of visible features may be used. For example, the torque value indicia 50 may be formed from a plurality of component indicia (e.g., a plurality of rings). In this way, the number of component markers can be used as an indication of discrete torque values. For example, a modular drive head 40 having four rings may have different discrete torque values than a modular drive head 40 having two rings.
According to some exemplary embodiments, the torque value indicia 50 may be positioned on the modular drive head 40 at a location that is not hidden by the operator when the rotary power tool assembly is in use. In this regard, the visibility of the torque value indicia 50 provides substantial utility in the context of manufacturing compliance. In this way, it is helpful to place the torque value indicia 50 in a highly visible position on the modular drive head 40. In this regard, for example, a user of a pistol-designed rotary power tool assembly 10 (e.g., a power screwdriver or nut runner) may typically grasp the assembly with a first hand at the trigger handle and then place a second hand adjacent the working tip 48 or collet 46 to control the placement of the working tip 48. To this end, the torque value indicia 50 may be placed rearwardly (i.e., further away from the working tip 48 and at or near the interface 60) to avoid the torque value indicia 50 being covered by the second pilot hand of the user.
Additionally, according to some exemplary embodiments, the torque value indicia 50 may include a ring. In this regard, the ring may extend around the circumference of the modular drive head 40. In this manner, the torque value indicia 50 may be viewed from either side of the rotary power tool assembly 10. Additionally, the width of the ring may be selected to increase the visibility of the torque value indicia 50. In this regard, the width of the ring may be greater than 0.25 inches to increase the visibility of the ring from distances such as 10 feet or more. Further, according to some exemplary embodiments, the torque value indicia 50 may also include light reflective features to increase the visibility of the visible features of the torque value indicia 50. In this regard, the torque value indicia 50 may include different light reflecting features (e.g., surfaces or materials using techniques such as glass beads or microprismatic methods) that allow the torque value indicia 50 to flash or sparkle a certain color in certain lights.
Referring now to fig. 2, a rotary power tool accessory system 200 is shown. In this regard, the system 200 includes a plurality of modular drive heads that are removably connectable to the rotodynamic base 250. The system 200 may include modular drive heads 210, 220, and 230, each of which may be the same or similar to modular drive head 40 described above. However, each modular drive head 210, 220, and 230 may have different discrete torque values, and thus also different visual characteristics of their respective torque value indicators 215, 225, and 235, each of which may be formed in the same or similar manner as described with respect to torque value indicator 50. Further, each modular drive head 210, 220, and 230 may be configured to be detachably connected to the rotational power base 250, each modular drive head including a respective torque control clutch to limit torque output to a respective discrete torque value.
In the exemplary embodiment shown in fig. 2, torque value indicators 215, 225, and 235 are formed as rings that wrap around the circumference of the respective modular drive heads 210, 220, and 230 at a location closer to the interface end of the modular drive heads opposite the working tip. According to some exemplary embodiments, each ring may have a width greater than 0.25 inches. According to some exemplary embodiments, the colors and discrete torque values may be defined as provided in table 300 shown in fig. 3. In this regard, for example, the modular drive head 210 with a yellow torque value indicia 215 will have a discrete torque value of 3Nm (newton meters). In addition, the modular drive head 220 with the green torque value indicia 225 will have a discrete torque value of 4 Nm. Finally, the modular drive head 230 with orange torque value indicia 235 will have a discrete torque value of 5 Nm.
Referring now to FIG. 4, an exemplary manufacturing environment 400 is illustrated. In this regard, the manufacturing environment 400 may include an assembly line 430 that passes through the manufacturing task area 410 and the manufacturing task area 420. A particular first manufacturing task (e.g., fastener application) may be performed in the manufacturing task area 410 that requires a certain torque. The manufacturing worker 412 performs a first manufacturing task in the manufacturing task area 410 using the rotary power tool assembly 414 and the manufacturing worker 416 performs a first manufacturing task using the rotary power tool assembly 418. Similarly, a particular second manufacturing task (e.g., fastener application) may be performed in a manufacturing task area 420 that requires a certain torque (e.g., which may be different from the first manufacturing task). The manufacturing worker 422 performs a second manufacturing task in the manufacturing task area 420 using the rotary power tool assembly 424 and the manufacturing worker 426 performs the second manufacturing task using the rotary power tool assembly 428.
Supervisor 442 also resides within manufacturing environment 400. In this regard, according to some example embodiments, the supervisor 442 may remain in the supervisor area 440. The supervision region 440 may be located at a distance from the manufacturing task regions 410 and 420. For example, the supervision area 440 may be more than 10 feet from the task areas 410 and 420, and may be up to 50 feet from the task areas 410 and 420.
However, according to various exemplary embodiments, due to the visibility of the torque value indicia on the modular drive head of the rotary power tool assembly, the supervisor 442 at a distance is still able to verify that the correct torque is being applied for the first manufacturing task and the second manufacturing task. The supervisor 442 may need to simply view the torque value indicia of the rotary power tool assembly, as indicated by the supervisor 442's dashed line of sight. In this way, the supervisor 442 is able to visually verify that the rotary power tool assembly operating on the first manufacturing task has a first torque value indicia that conforms to the first visual characteristics of the manufacturing process. The supervisor 442 is also capable of visually verifying that a rotary power tool assembly operating on a second manufacturing task has a second torque value indicia with a second visual characteristic. According to some example embodiments, the first manufacturing task may include tightening a first fastener on a product moving along assembly line 430, and the second manufacturing task includes tightening a second fastener on a product moving along assembly line 430.
Referring now to fig. 5, an exemplary method for manufacturing compliance utilizing the exemplary embodiments described herein is provided. In this regard, at 500, an example method may include visually verifying that a first rotary power tool assembly operating on a first manufacturing task has a first torque value indicia with a first visual characteristic (e.g., a color). The first visual characteristic may indicate that the first rotary power base of the first rotary power tool assembly is attached to the first modular drive head. The first modular drive head may have a first non-adjustable torque control clutch operative to limit the applied torque to a first discrete torque value. The first discrete torque value may be associated with a first visual characteristic, and the first discrete torque value may be selected for a first manufacturing task (e.g., based on the type of fastener and the material being fastened). The first modular drive head may also be detachably connected to the first rotodynamic base.
At 510, the exemplary method may include visually verifying that a second rotary power tool assembly operating on a second manufacturing task has a second torque value indicia with a second visual characteristic. In this regard, the second visual characteristic may indicate that a second rotary power base of a second rotary power tool assembly is attached to the second modular drive head. The second modular drive head may have a second non-adjustable torque control clutch that limits the applied torque to a second discrete torque value. The second discrete torque value may be associated with a second visual characteristic, and the second discrete torque value may be selected for a second manufacturing task.
The second modular drive head may also be detachably connected to the second rotodynamic base.
Further, with respect to the example method, the second discrete torque value may be different from the first discrete torque value, and the second visible feature may be visually different from the first visible feature. Additionally, according to some example embodiments, the example method may further include locking the first modular drive head to the first rotodynamic base such that a user person cannot detach the first modular drive head from the first rotodynamic base (e.g., without the aid of a supervisor having a key). Additionally, according to some example embodiments, the example method may further include locking the second modular drive head to the second rotary power base such that a user person cannot detach the second modular drive head from the second rotary power base (e.g., without the aid of a supervisor having a key).
